Geosynthetics - Determination of the long term protection efficiency of geosynthetics in contact with geosynthetic barriers

This European Standard is an index test used to determine the efficiency with which a geosynthetic product will protect a geosynthetic barrier or other contact surface against the mechanical long term effects of static point loads.
The test is performed on the geosynthetic product in isolation. It measures the strains experienced by a geosynthetic product in contact with a deformable pad.
NOTE   Other properties relevant to the protection of geosynthetic barriers against differing actions are covered by other standards, e.g. dynamic perforation is covered in EN ISO 13433.
A related performance test simulating specific site conditions is described in Annex B (informative).

Geokunststoffe - Bestimmung der langfristigen Schutzwirksamkeit von Geokunststoffen im Kontakt mit geosynthetischen Dichtungsbahnen

Diese Europäische Norm beschreibt ein Index-Prüfverfahren zur Bestimmung der Wirksamkeit, mit der ein Geokunststoff eine geosynthetische Dichtungsbahn oder eine andere Kontaktfläche gegen die mechanische Langzeiteinwirkung statischer Punktbelastungen schützen wird.
Die Prüfung wird allein am Geokunststoff ausgeführt. Sie misst die festgestellten Dehnungen an einem Geokunststoff, der im Kontakt mit einer verformbaren Unterlage steht.
ANMERKUNG   Andere Eigenschaften, die für den Schutz von geosynthetischen Dichtungsbahnen gegen verschiedene Einwirkungen von Bedeutung sind, sind durch andere Normen abgedeckt, z. B. dynamischer Durchschlag in EN ISO 13433.
Eine entsprechende Leistungsprüfung, die besondere Baustellenbedingungen simuliert, ist in Anhang B (informativ) beschrieben.

Géosynthétiques - Détermination de l'efficacité de protection à long terme des géosynthétiques en contact avec les géomembranes

La présente Norme européenne est un essai de référence utilisé pour déterminer l’efficacité avec laquelle un produit géosynthétique protège une géomembrane ou une autre surface de contact contre les effets mécaniques à long terme des charges statiques ponctuelles.
L’essai est effectué sur le produit géosynthétique isolé. Il mesure les déformations subies par un produit géosynthétique en contact avec un support déformable.
NOTE   D’autres propriétés relatives à la protection des géomembranes contre différentes actions sont couvertes par d’autres normes. Par exemple, la perforation dynamique est traitée dans l’EN ISO 13433.
Un essai de performance voisin simulant les conditions spécifiques sur site est décrit dans l’Annexe B (informative).

Geotekstilije in geotekstilijam sorodni proizvodi - Ugotavljanje učinkovitosti dolgotrajne zaščite geotekstilij v primeru geotekstilnih ovir

Ta evropski standard je pokazateljski preskus, s katerim se ugotavlja učinkovitost zaščite, ki jo geotekstilije oz. geotekstilijam sorodni proizvodi zagotavljajo za geotekstilno oviro ali drugo kontaktno površino ob dolgotrajni mehanski statični točkovni obremenitvi.
Preskus se izvede na geotekstilijah oz. geotekstilijam sorodnih proizvodih v izolaciji. S tem preskusom se izmerijo deformacije geotekstilij oz. geotekstilijam sorodnih proizvodov ob stiku z deformljivo oblogo.
OPOMBA: Druge lastnosti v zvezi z zaščito geotekstilnih ovir pred različnimi dejavniki so zajete v drugih standardih (npr. dinamična perforacija je zajeta v standardu EN 918).
Soroden preskus učinkovitosti s simulacijo specifičnih pogojev mesta uporabe je opisan v dodatku B.

EN 13719:2016 (E) 6 4 Principle Load is applied through a simulated standard aggregate on to the geosynthetic specimen, which is supported on a simulated standard subgrade for a standard time. The local strain in the lower surface of the geosynthetic is measured and used to determine the protection efficiency. 5 Apparatus 5.1 Cylinder A smooth sided steel cylinder having an internal diameter between 300 mm and 500 mm. NOTE The cylinder can be in sections bolted together at flanged joints to facilitate setting up and dismantling. 5.2 Lower steel plate 20 mm minimum thickness mild steel plate with a diameter 4 mm less than that of the cylinder with a tolerance of ± 1 mm to allow it to vertically move freely within the cylinder. The lower steel plate shall be supported in a way that the effective normal stress can be measured to an accuracy of 1 %. 5.3 Dense rubber pad A (25 ± 1) mm thickness rubber pad having a diameter similar to the lower steel plate and a hardness of (50 ± 5) Shore A, determined in accordance with ISO 7619-1. The rubber pad should be checked for hardness on a grid no greater than 20 mm at intervals not exceeding 12 months. If the pad is outside the hardness tolerance at any location or exhibits signs of permanent mechanical damage, it shall not be used. 5.4 Lead sheet A circular lead disc shall be used. It shall have a thickness of (1,3 ± 0,1) mm, grade 3 lead to EN 12588 or similar, with deformation characteristics and thickness in accordance with the requirements of Annex A and with a diameter sim
